TALLAHASSEE, Fla. (AP) - No. 11 Florida State heads into the final third of its schedule trying to cure a midseason bout of sloppiness.

The Seminoles lost two of their five fumbles last week in addition to a dozen penalties that cost them another 121 yards in a sluggish 33-20 win at Miami.

The Seminoles (7-1, 4-1 Atlantic Coast Conference) are changing their punt returner for Saturday's game against Duke, which leads the ACC's Coastal Division. Sophomore defensive back Tyler Hunter will take over the punt return duties from Rashad Greene in a significant lineup change this week by Florida State coach Jimbo Fisher.

And the Seminoles are at home where they've been a far more dominant team this season, averaging 55.4 points a game, more than twice what they've averaged in road games.
